[0002] The screen punching machine is a machine that processes metal coils into specific products. It has been widely used in industrial production. Its production line consists of three parts: an uncoiler, a feeder and a punching machine. In order to make the screen punching machine production line have a high level of automation and meet the needs of metal processing, a high-performance PLC control system has been developed and designed. The control system is based on PLC and also includes components such as touch screen and servo drive device.
